(adsbygoogle = window.adsbygoogle || []).push({}); I have an iPhone 3G jailbroken running iOS 3.1.2, and it won't connect to my computer. I plug it in, and it says, "USB Device Not Recognized".

What should I do?

Well, first of all make sure its not the usb, try it by using a plug. Second, try blowing in the laptop and usb also iphone to make sure no dust has got caught in it. Try opening itunes and plug it, put it in recovery mode, try other usbs and see if its the same error. Any new hardware that could of contained a virus?

Hopefully this has helped!

Update your itunes maybe?
or Download Wifi Sync from cydia and on your computer You must login or register to view this content.
No usb needed

UPDATE: Now it worked, then i got the white screen of death! :cry:

It won't connect to iTunes, and the tuening off doesn't help either

What should I do?

try a dfu restore that might work
